I'll bet you have more damage than the Gib.........you have 300:1 motors. Is there a residential Fridge in that slide? If so it's too heavy for 300:1 motors, need the 500:1 motors. Just went through 4.5 months of pain with ours. Jayco knows they have major issues, they replaced everything on our slide.
